Killcam

[Painkiller]

I want to create a kill cam for hl2dm, where you see a picture of the enemy that killed you with a black and white filter"


Thanks in Advance

Nobody a Idia ?

I'm not sure this is even possible from a plugin standpoint.

Yes this is possible, you'll have to attach the player's camera to another entity, likely and enable a screen overlay that makes everything black and white, it won't look terribly good but it might work.

Hello Python team and community,

Changing the _player_death() function to this should fix that:

Syntax: Select all

def _player_death(game_event):
    userid = game_event.get_int('userid')
    attacker = game_event.get_int('attacker')
    if attacker not in (userid, 0):
        Delay(0.5, activate_cam, (userid, attacker))

I noticed you also asked for the screen to go black and white in your original request. I've added that.. and rewrote the plugin, here you go :

[VinciT]

It seems your Source.Python is outdated. Try running the sp update server command or update it manually.

Edit: If you don't feel like updating for some reason, you can just change the __init__() function to this:

Syntax: Select all

def __init__(self, index):
    """Initializes the object."""
    super().__init__(index)
    self.mono = False

ok thanks

I get this now in killcam log. and if you could, could you make it so you have to use mouse button 1 to spawn? I am using the 2nd script on on this page, the one that gives black and white.

Fixed the issue and added a way to disable the automatic respawn - set KILLCAM_DURATION to 0 to get the behavior you want.
The updated plugin can be found in this post.

[daren adler]

OK i will check it out . Thank you again

[daren adler]

OK i will check it out . Thank you again

**update** I put it to 0 and i still have to hit w or a or d to spawn, (was hoping for mouse button 1) but if not thats ok,,i get no errors, thank you.

[PEACE]

Hey All ,

I tried this and it works good with auto respawn on

[VinciT]

OK i will check it out . Thank you again

**update** I put it to 0 and i still have to hit w or a or d to spawn, (was hoping for mouse button 1) but if not thats ok,,i get no errors, thank you.

Huh, that's odd.. On my server left click (+attack) respawns me. Heading out right now, when I come back I'll see if I can figure something out.

OK will do. Works great Thank you
